EJ3108 | EtherCAT plug-in module, 8-channel analog input, voltage, ±10 V, 16 bit
EtherCAT plug-in modules of the EJ series
Efficient series machine manufacturing: plug-and-play in the control cabinet
Measurement technology easily configured: Analog EtherCAT input terminals.
Measurement technology simply integrated: With the analog EtherCAT Terminals.
EtherCAT plug-in modules: Bus Terminals for circuit boards
The EJ3108 EtherCAT plug-in module processes signals in the range between -10 and +10 V. The voltage is digitized to a resolution of 16 bits, and is transmitted, electrically isolated, to the higher-level automation device. Of the eight input channels, six are designed as differential and two as single-ended inputs. The signal state is indicated by light emitting diodes.
